The biparietal diameter (BPD) in 202 rural Tanzanian newborns was measured and correlated to maturity and body weight. The mean BPD at birth was 9.0 cm. The average body weight was 2642 g. Fetal maturity was determined by Petrussa score, serving as an estimate for gestational age. The mean gestational age of the 202 newborns was 39 weeks. The average body weight of the mature babies (gestationa...

In this paper a Glial Ratio (g-ratio) mix hybrids of 67% Sigmoid and 33% Radial functions (HSCR-BFgr) based on Particle swarm optimisation with the highest survivability of all possible routing redundancies, reliability, efficiency, fault tolerant with minimum fitness error is proposed for underground rescue operation. Nonlinear weights of cosine and sine were imposed on the g-ratio hybrids. In...

Using a developed laser light-scattering (LLS) procedure, we accomplished the characterization of an unfractionated polyimide (UPI) in CHCl3 at 25°C. The Laplace inversion of precisely measured intensity–intensity time correlation function from dynamic LLS leads us first to an estimate of the characteristic line-width distribution G(G), and then to the translational diffusion coefficient distri...

OBJECTIVE Investigate the effect of transient hyperglycemic intake (analogous to snacking on high glycaemic foods) in the third trimester of pregnancy on offspring birthweight and subsequent growth in sheep. DESIGN Randomised trial. SETTING University research farm. SAMPLE Third trimester pregnant ewes. METHODS Ewes were blocked on weight, age and litter size and were randomly assigned ...

Let G be a graph. A set S of vertices in G dominates the graph if every vertex of G is either in S or a neighbor of a vertex in S. Finding a minimal cardinality set which dominates the graph is an NP-complete problem. The graph G is well-dominated if all its minimal dominating sets are of the same cardinality. The complexity status of recognizing well-dominated graphs is not known. We show that...

CONTEXT AND OBJECTIVE Excessive gestational weight gain is related to many complications (both maternal and fetal), such as macrosomia. The most common complications in macrosomic fetuses include: increased risk of intrauterine death, need for intensive care, fractures, neonatal hyperbilirubinemia, paralysis of the brachial plexus and obesity in childhood and adulthood. The aim of this study wa...

Let $kgeq 1$ be an integer, and let $G$ be a graph. A {it$k$-rainbow dominating function} (or a {it $k$-RDF}) of $G$ is afunction $f$ from the vertex set $V(G)$ to the family of all subsetsof ${1,2,ldots ,k}$ such that for every $vin V(G)$ with$f(v)=emptyset $, the condition $bigcup_{uinN_{G}(v)}f(u)={1,2,ldots,k}$ is fulfilled, where $N_{G}(v)$ isthe open neighborhood of $v$. The {it weight} o...

Dissipative particle dynamics (DPD) simulations have been carried out to study the hydrated morphology of 3M perfluorosulfonic acid (PFSA) fuel cell membranes as a function of the equivalent weight (EW), molecular weight (MW), and hydration level. The 3M PFSA ionomers were modeled using typical EWs of 578, 640, and 790 g/mol, and molecular weights were varied from about 45,000 to 90,000 g/mol i...

Obesity is a chronic metabolic condition with important public health implications associated with numerous co-morbidities including cardiovascular disease, insulin resistance, and hypertension. The renin angiotensin system (RAS), best known for its involvement in cardiovascular control and body fluid homeostasis has, more recently, been implicated in regulation of energy balance. Interference ...

In Uruguay, there was no information about the variations degree in Bothrops pubescens venoms until the present work, in which we investigated intraspecific venom variation using polyacrylamide gel electrophoresis (SDS-PAGE). We found some differences in the venom protein profile; however, they were not related to the parameters studied (geographic distribution, weight, sex, and captivity time)...
